j- {This invention? relates to driving -for thread' guides, particularly 'for'fcop winding "machines; provided with a g ea'r drivefhaving exchangeable reducing gears drivingly' connected member of thethread guide? --Acco rdingnto the invention, a worm gear is arranged for cooperation with the; exchangeable reducing gear drive,

In producing cops, reo'en more and more for the purpose 'of' avoidinjg eventual loosening of the thread; coil as; much as possible. Consequently, the latest development' in .the construction -oficop winding'machines follows this tendency. "Since theproduc mm of 'crosswinds "has abovg'all theeffectf' of reducing .the velocity ofwindingytheernploy ment of aback gearfldrive "was resorted to with *a view to minimizingthisdrawback in winding,

thread material is preserved. and the formation I of flulT-reduced, while, on the other hand, the said traversing-Ker guide spindle is axially recipxrocated free from shock, so that the setting up ofvibrations' of the machine is minimized. Since the pair ofgears l3, l4- rotates at relatively 'low speed the driving arrangement runs practically noiselessly; I a a InLthe-accompanying drawing two embodiments ofthe invention are illustratedby way Fig. 1 shows an elevation of a first embodiment with the traversing member in an axial section;

. and the-hollow shaftof which is firmly connected lengths of threadzca'n wound'on thewinding carrier. v M g The driving arrangement for thread guides accordin'gqtothisinventionpermits, by virtue of the worm gea the speed ofjre'volution of the.

"winding vspindle to" be transmitted to the travers- "ing member of the thread guide only at afc'o'nsiderably reduced rateso that said memb'enis driven at'relatively low speed, whilethewinding spindle runs at a high speed. Consequently; the

thread is "wound on the winding carrier atgreat velocity but" distributed'by the thread guide relatively slowlyso that the thread is crossed only "slightlyifat an and is thusparallel wound by taking advantage "of a the .feasibilitypf windin themos't part of the various kinds, of thread'in what may betermed semi or full, parallel (winds without'impairing the thread. By; means of ex- I changing of reducing gearsor the gear drive the velocity at which thethread guide is driven canbe adjustedmore exactly in accordance with the propentiesof thefth fflad material, K

a worm, wheel H] which is mounted for rotation Fig. 2' is a; top plan view of Fig. 1, and

"Fig.3 shows an axial section of a second bodiment. v

. .In this instance, thelcop winding machine used .isprovided with-a gear box I through which passes awindingspindle 2 carrying a coupling member 3 which is rotatably arranged thereon to the. driving disc 4, serving for cooperating with a wedge shaped belt (not shown) which can be actuated from a motor. The coupling member-3 ,is adapted to cooperate with a mating coupling member 5, which is also carried by the vwinding spindle 2, and is connected for common rotation with said spindle 2, by means of a spline B beingv arranged in a groove, but so as to be axially displaceable on'said spindle by means of .an arm '1 which is secured to a control shaft 8 which is in turn cont-rolled by means not shown. The parts I and 8 inclusive of accessories are omitted from Fig. 1'. A worm 9 is firmly secured to the winding spindle 2 and inter-meshes with on a; vertical axle pin l I fixed to the gear box I.

. Fig. 3 shows, for, the purpose of illustration, the

winding spindle Ztobe oifset relative to its position in Fig. 2together with the worm 9. On the axle pin ll is further mounted a gear I3 which is connected to the-worm wheel It! for conjoint rotation by means of a pin I2, Thegear l3 cooperateswith a, companion gear l4 which is arrangedon avertical axle I5 mounted in the gear box I. r ,1 i In the firstembodiment (Figs. 1 and 2) the companion gear .14 is coupled, by means of a Q pin 16,120 thehub ll of atraversing disc I8 which is mounted for rotation on the axle l5 and controls, by means of a circumferential groove, a

two-armedrockable lever l9 mounted at 20. The

' moved through a traverse of greater or shorter length when the traversing. member l8.rotates.

In Fig. 2, the conical frictionicouplingl3, '-is shown in condition of operation resulting in the rotative movement of the driving disc or pulley 4 being transmitted to the winding spindle 2.

The empty spool (not shown) when .inserted in the head 2' of the winding spindle-is engaged at its second end by a counter holder (not shown).

vterial. To. this end the gears l3, and l4 "can't be taken-off the vertical axles H .and inxthe upward direction out of the gear box, I. Byathis means the replacing of the pair. otgearsisgreatly ,facilitated, for thevreason, that for. doing this Work ample'free space is. available. aboveuthengear box.

In the second embodiment (Fig. .3) between the wormdriveil, Ill and thetraversing disc l8 asecond pair'of gears 23, 24. is providedrapart from the pair of gears l3, M, for further reducing the speed of revolution of the itraversing disc-I8. The .-gear.23 is:.firmly.keyed totheaxle I 5, which in: this case. is 1 rotatably arranged I on -the;,gear box I, andthegear 244's zsecuredrtothe; hub; I! 'on the :traversing disc 5 I 8 *which i in this instance is rotatably mounted on-theaxle As wilLbe readily. seen, the arrangement may be-such that the gears :23 and "2-4 also can-b'e replaced, ifdesired. T

.In the two.embodiments descr-ibed 'the worm Wheel is arranged in advance, 1 considered -'-with respect to the direction r of transmission L of "the driving zmovement, of :the change speed back gear .drive. If required the arrangement m'ay .beireversed by arranging the" back gear drive in advance of the worm drive.

.As shown' in-Figs. land 2 thedrive coupling L3,'-5 is protected against=the-entry-of dustyfluff .etc. by beinghoused in-a-bearingmounting of its parts in adaptation to'high driving speeds. 1 During the. operation the I driving disc 4 carried by the Winding spindle 2 is-continually driven, whilst by axially shifting one of the-halves'of :the drive coupling 3, 5, being also carried' bythe' winding spindle 2, the disconnecting of theWinding spindle 2, that is, the 'drive'coupling is efiected. This arrangement results in continuously reliablyguiding" the displaceable half 5 of the drive coupling.

The winding spindle 2 transmitsits- .rotative movement to the gear I3 viatheyvorm ,drive 9, ID at considerably reduced speed and -,thus to the traversing disc t8'via the companion gear by reducing its speed of revolution "once ,more, so that-the thread guide carrier rod 22 ie-accordingly axiallyreciprocated.for the purxpose of effecting the cop building operation. .By. replacing the. pair of gears l 3, l4 bygearseof difierent diameters the driving speed for the thread guide can be adapted-to the] thread-mar,
